1. A soil sample is taken from a small test hole in a soil borrow pit. The volume of the test hole is 5 ft. The wet mass of the soil is 18 kg and the dry mass is 21 kg. The specific gravity of the soil solids is 2.65. ( m 35. 3147ft)(1 kge 2.205 lb) ( 1 lb= 0.2248 N) Determine: a. Wet and dry density (Mg/m) b. Wet and dry unit weight (pcf) C. Water content (%)...
